"The stores and their franchisees represent many of the diversified aspects of the Subway chain that have enabled it to grow so successfully over the years," said Subway spokesman Les Winograd.

Subway has a diversity of restaurant concepts across the globe. For example the new Hong Kong store seats only 10 customers, the one in Germany is only 140 square feet, the North Carolina restaurant is 1,500 square feet and the Windsor, Ontario location is inside a Home Depot.
